Cable-stayed bridge construction method

The tension in the span-type cable-stayed bridge, in the main span by using a compression, tension cables in the whole cable-stayed bridge may occur by allowing the tensile stress to the deck plate is disclosed a method for reducing the size of the maximum compressive stress. In using the deck segment it is provided on main span tension means including a tension device and tendons reducing the size of the maximum compressive stress acting on the deck segments of the main span cross-section as it is possible to reduce the cross-sectional area of ​​the deck segments of the main span, for this purpose both sides of the main span deck segment is provided a lateral fixing block enables the removable fixing of the tension and tendons, by the lateral fixing block will be written.
